The importance of getting that info is growing with each strange detail you post from the Linux system.

We don't know which routing and IP info on the Linux system is wrong vs. merely strange. By comparing to the corresponding info on the Windows system, you can get a better idea what is wrong.

You may need admin privileges to run ipconfig in Windows. I'm used to XP, where you just run it. I found Vista instructions

Code:

1. Click Start
2. Click All Programs expand the Accessories menu
3. In the Accessories menu, Right Click Command Prompt and choose Run as administrator
4. Type ipconfig hit enter

I'm not sure of Win7 instructions for that.

My wlan is off. I also unchecked 'enable wireless' in gnm. Also, all surrounding wlans are WEP, and I can't even hack my own dsl router, let alone a neighbours! Rule out wireless!

I will try the line in BOOTPROTO=dhcp, but I'm already sure my machine uses it: surely someone would have told me if I have a fixed IP?? And I would have to enter it somewhere on this machine.

Here the gen!

It's a bit long so I added it as attachment: The only thing I see, as an amateur, is he has gateway 192.162.1.1, whereas I have something different. Does that explain why I can't open 192.162.1.1? As you said, I am out of the inner network, and my request addresses the gateway router??

Am I looking at buying a router to put in front of the router?? Or just for home use?

Is Default route the same as gateway??

The part I was looking for in your Windows ipconfig output is

Code:

   IPv4 Address. . . . . . . . . . . : 192.168.1.3
   Subnet Mask . . . . . . . . . . . : 255.255.255.0
   Default Gateway . . . . . . . . . : 192.168.1.1

That is perfectly typical for the results of a DHCP connection of a Windows or Linux computer to a typical home router.

So what we're trying to figure out is what setting in the Linux laptop stops it from getting similar information from DHCP on each reboot.

Why do you think you need another router?

I'm pretty sure you just need to change some setting in the Linux network configuration that is currently either overriding or disabling DHCP. After finding and fixing whatever that is, I think you'll need to reboot the laptop to get the new settings to take effect.

Just rebooted with the changed ifcfg-eth0 file BOOTPROTO=dhcp

No change in the status quo!

Interesting development: this morning I made a new wired connection: Homewired, manual IP

I gave it 192.168.1.10, 255.255.255.0 Gateway 192.168.1.1 DNS 218.2.135.1

Now, using that, I can connect to my son's computer, and the router. Sadly, the router page is only in Chinese, and I am still learning, so I won't do anything there yet. From the Win 7 computer I still can't see my share.

Also sadly, I can't reach the internet from Homewired. But still, this is progress!!

Any tips??

Try using 192.168.1.1 for DNS in addition to using it for Gateway.

Nope, no joy!!
